In order to assess the yield and their components of 18 barley genotypes and two varieties as control groups (Mahoor and Khoram), an experiment was conducted in a randomized complete block design with three replicates in the crop year of 89-90 in Moghan. Significant differences between tested genotypes were observed for the most traits. To traits two clusters were identified with Ward's method and standardized data. In the first cluster the total plant weight, seed weight per plant, straw weight, grain number per spike, the number of spikelet's, peduncle length, fertile tiller number and plant height were more than the total average. While the second cluster, in terms of grain yield, grain weight per spike, spike length, number of tillers and total protein content was greater than the total average value. The result can be stated that the first group of lines 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 16 and 17 could be introduced as the superior group. These lines could be used in breeding programs. Based on factor analysis, four factors explained 76.239% of the total variation. The main first factors explained 28.155% of the total variation were introduced as a functional factor.
